OTLP Metrics Support

- TLS support for logs - Client certificate authentication support for secure OTLP log export
- Improved logfmt formatting - Better structured output for log messages
Tracing Improvements

Build System

$(date +%s)) in addition to RFC3339 format - Simplified build commands - Reduces complexity of ldflags injection while maintaining backward compatibility
- Consistent output format - All build times normalize to RFC3339 format regardless of input
